Product Description
Dean RWA2096 Compact High-Temperature Hot Water, Ethylene Glycol & Propylene Glycol Pump
The Dean RWA2096 is a compact, air-cooled centrifugal process pump engineered for pressurized hot water, ethylene glycol, and propylene glycol circulation loops up to 350°F (177°C) without external cooling water. Built to ANSI B73.1 AA envelope dimensions (Print RA-1047) with ASME Class 150 Flat Face flanges across 3 sizes (1x1.5x6, 1.5x3x6, and 1x1.5x8), it incorporates a top-mounted 304SS Vapor Eliminator (SKU 9320215), a hot-water mechanical seal with Aflas elastomers, a replaceable 316SS shaft sleeve, and PLS10 Teflon casing gaskets.
Key Engineering Highlights:
- Compact Hot-Water & Glycol Design (ANSI B73.1 AA): Matches standard ANSI AA mounting dimensions (CP = 17.50", L = 13.50", Y = 4.00", D = 5.25") while eliminating external seal flush water.
- 304SS Top-Mounted Vapor Eliminator (#26J, SKU 9320215): Automatically vents trapped air and vapor from the seal chamber so the mechanical seal faces remain lubricated in hot water and glycol service.
- Hot-Water Mechanical Seal, 316SS Dry Sleeve & Teflon Gaskets: Equipped with hot-water carbon vs. silicon carbide seal faces, Aflas elastomers, a 316SS shaft sleeve, and PLS10 Teflon casing gaskets.
- Class 22 Ductile Iron Pressure Casing: Foot-mounted volute casing with ASME B16.5 Class 150 FF flanges and back pull-out rotating assembly.
- Configurable Bare Pump or Complete Motor Package: Order above as a bare shaft pump or assembled on a baseplate with coupling and TEFC motor.
